Title: Bag machines
IPC: B31B50/92
Filed: 1969-11-14
Abstract: In a machine for making bags by intermittently feeding, sealing, and severing a thermoplastic web TW by a reciprocable seal bar assembly 14 the latter is rendered inoperative when the web feed is momentarily interrupted, and actuating means for reciprocating the seal bar assembly 14 can be continued while the seal bar assembly is arrested by interrupting a connection between the actuating means and the seal bar assembly. As shown, a folded and gusseted web TW is intermittently drawn by rolls 12, 12 beneath the seal bar assembly 14 and over a co-operating seal roll 56, the reciprocal movements of the seal bar assembly 14 being coordinated with the web feed to sever and weld the web TW transversely and form individual bags which are transported, between upper and lower conveyers 60, 64, to a stacking table 18 where they are stacked against sheet metal frames 96. The seal bar assembly 14 comprises a seal bar 54 connected by metal clips 52 to a beam 48 which has stub shafts 50 mounted in respective posts 46 each of which rests upon a plate 84 secured to the upper end of a respective push rod 74. A roller 78, at the lower end of each rod 74 is loaded by a spring 92 against a corresponding cam plate 80 which is keyed to a drive shaft 82 so that the seal bar assembly 14 is intermittently raised and lowered to cooperate with the seal roll 56 during normal running of the machine. The machine can be temporarily stopped, e.g. while a completed stack of bags is being removed from the table 18, by pressing a foot switch FS which causes pneumatic cylinders 28 to extend their pistonrods 36 so that nylon blocks 38 on the ends thereof are moved to engage beneath blocks 44 on the posts 46 and hold them raised in an inoperative position while the machine is stopped. The posts 46 can also be held raised and inoperative while the machine is running by actuating pneumatic cylinders 86 each of which is mounted on a respective plate 84 and has an actuating rod 88 connected to an ear 90 on the post 46, the upper end of each rod slidingly engaging in openings in the respective posts 46 with lost motion. The switch (FS) can be over-ridden by a toggle switch (S9) for longer shut - down periods. The upper conveyer 64 is movable toward and away from the lower conveyer 60 in synchronism with the intermittent motion of the machine. A limit switch (5LS), providing a machine timed switching for count pulses, has two sets of'contacts, one for pulsing a totalizer counter and the other for pulsing a predetermined counter. A limit switch (6LS) also provides a machine timed pulse which ensures stopping and starting the machine at a certain point in its cycle to eliminate the possibility of a partial draw of the thermoplastic web. The circuit diagram of the electrical control circuit for initiating an interrupt cycle of the machine is described with reference to Fig. 7, not shown.

Title: Tensioning tool with self-energizing gripper plug
IPC: B65B67/00
Filed: 1977-01-21
Abstract: A strapping tool having a resiliently biased feed wheel and a gripper plug in the base thereof. The feed wheel is movable relative to the gripper plug to permit loading and releasing of overlapping loop strap ends therebetween. The gripper plug has a concave gripping surface and is pivotally mounted in the base of the tensioning tool with the pivotal axis parallel to the axis of the feed wheel, thus permitting rotation of the gripper plug about its pivotal axis under the influence of the force on the overlapped strap ends during the tensioning action by the feed wheel. The interaction between the feed wheel surface and the concave gripping surface of the gripper plug distributes the impressed force therebetween uniformly over the segment of the overlapping strap ends lying between the two surfaces to preclude pinching of the strap.
Patent ES-460472-A1 (ES)
Title: Control of torch position and travel in automatic welding
IPC: B23K9/02
Filed: 1977-07-06
Abstract: To maintain control of arc position in travel along a predetermined welding path, wherein the arc or equivalent heat source is given at least a minimal lateral reciprocation, an electrical characteristic, such as current, is sampled to obtain a continuous signal containing a component which varies with lateral position of the heat source. The first signal is also sampled at the extreme lateral positions of the arc to obtain comparable signal elements which are accumulated, amplified, compared with each other and/or with reference signals, and resultant outputs are used to initiate corrective action. This action may involve giving warning to a human operator or it may involve partial or full control of a physical or mechanical correction procedure. A general application is to the welding of a groove formed between adjacent work pieces. A more specific application is to weld joints involving narrow gaps between length of large pipe in pipeline building. The invention is applicable also to situations wherein lateral oscillation is not really required for gap filling but is used merely as a means to isolate control signals for maintaining an accurate center or main line travel position of the arc of heat source. Moreover, the invention may have a more general application, wherever guidance is desired along a main path that contains any element that effects signal amplitude of a probe characteristic relative to the lateral position of the element where the signal may be masked by noise.
Patent ES-466295-A1 (ES)
Title: Method and apparatus for conveying particulate material
IPC: B30B11/22
Filed: 1978-01-24
Abstract: A method and apparatus for conveying particulate material of the type wherein it is desired that the material be simultaneously pre-compacted from a generally loose state to a more or less solid "plug" state. A screw conveyor is arranged to deliver loose particulate material to an intermediate chamber at the end of the screw conveyor means wherein the material is pre-compacted by the action of the screw conveyor. Following the intermediate chamber, a piston reciprocating coaxially with the screw conveyor further urges the material in a direction coaxial with the centerline of the screw conveyor to further advance the material through a straight coaxial conduit within which the material becomes compacted to an increased degree of compactness, solely by the action of the reciprocating piston. The reciprocating piston has preferably an annular face, whose outside diagram is generally the same as that of the Industrial Design of the conduit. The second, high degree of compactness is thus achieved solely by the action of the piston. Accordingly, the mounting of the screw conveyor is not subjected to extreme forces. The device is capable of compacting, for instance, fibrous material of a relatively low fibre shear strength to an extremely high compactness without exceeding the fibre shear limit in the area of the screw conveyor. Frictional drag in the conduit following the apparatus may be increased by vanes protruding inside of the conveyor. The depth of the friction increasing vanes may be selectively adjustable.
